RF Choke

[The Howler]

Didn’t want to hijack The Ground plane vs metal mast thread.
I live in a area with some major high voltage lines running down the street in front of my house. I have grounded everything That Justme suggested in this thread. I would like to try the RF chokes, any suggestions on chokes that folks have had good luck with? I know absolutely Nothing about these.
Thanks, Greg

After research, I use PALOMAR ENGINEERS to make most purchases.

The two main choices I'd use...

NUMBER ONE: 8 turns of RG58 on a FT240-61 toroid. You can put it in a small plastic box and solder sockets onto the end to make it look nice. This will give you by far the best choking on 11m.

Second: 5 turns of RG213 or RG58, whichever you're using, on a 110mm/4.25" diameter non-metallic tube. Here in the UK plastic underground waste water pipe is the exact size. Has to be the exact number of turns and size as the coil is a tuned circuit so altering the dimensions alters the frequency it works on.

Ultimately though if you're getting noise from the power lines the only people who can sort that are the power company. It's worth reporting as it may be a pole transformer or line insulators going bad.
